Nasal cavity dilator

Abstract

The present invention provides a nasal dilator including: two intranasal stents (1) and a connecting band (2), wherein each of two ends of the connecting band (2) being symmetrically connected to one intranasal stent (1), each intranasal stent (1) having an elastic band-shape structure, each intranasal stent (1) has a straight-line shape, an arc-line shape, a bow shape, or a fold-line shape in a cross section perpendicular to a width direction of the elastic banded structure, each intranasal stent (1), along a length direction of the elastic band-shape structure, comprises: a nasal septum supporting section (3), a bending section (4), and a nasal alar dilating section (5), each intranasal stent (1) has a generally C-shape in a cross-section perpendicular to a central axis of nasal passages, wherein an opening of the C-shape faces towards a nasal base (11).

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the national phase entry of International Application No. PCT / CN2016 / 084306, filed on Jun. 1, 2016, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to the field of dilating device, especially to a nasal cavity dilator.BACKGROUND[0003]Currently, a considerable number of people are suffering from nasal obstruction disease (also known as rhinobyon). The narrowest part of the nasal cavity of the human body is the nasal valve area (intranasal hole). This nasal valve area is located in the deep part of the nasal vestibule and in front of the front-end of the inferior nasal concha. It is a long and narrow triangular region and is a part where the greatest nasal resistance exists. The nasal obstruction normally occurs in the nasal valve area and the front-end of the inferior nasal concha adjacent to the nasal valve area. Normally, the nasal obstruction is cau...

AI Technical Summary

Benefits of technology

The present invention provides a nasal dilator that overcomes the limitations of current nasal dilators such as low expansion strength and low adaptability to different nare shapes. The nasal dilator has the advantages of both band-shaped and columnar-shaped intranasal stents, which results in improved dilating ability, ventilation ability, applicability, and comfortableness.

Problems solved by technology

However, the cost of the operation is usually high and cannot fundamentally cure the deformation of the nasal passage.

Moreover, the removal of turbinate can cause “empty nose syndrome” and other sequelae, which will bring more pain to the patients.

The disadvantage of the columnar shape (or annular shape) intranasal stent is high air resistance and low adaptability to the nares of different shapes.

The disadvantage of the band-shaped intranasal stent is that the expansion strength in the two ends of the intranasal stent is insufficient.
